Systematization of basic divergent integrals in perturbation theory and renormalization group functions
(Elsevier, 2009-02)
We show that to n loop order the divergent content of a Feynman amplitude is spanned by a set of
basic (logarithmically divergent) integrals I
(i)
log(λ2), i = 1, 2,...,n, λ being the renormalization group scale,
which ...
